Why Is Earth Here?

Lileks seems to be a co-religionist with me:

You know, every so often I run across comments on message boards from the “12 Monkeys” demographic, the people who wish people would just disappear and leave the earth alone. If the Aftermath show has any message, it’s how useless the world would be without people. Without humans it’s just hunting and rutting, birthing and dying, a clock with no chimes. It’s always interesting how people romanticize Nature, and ascribe all manner of purpose and intelligence to it, lamenting the injuries people wreak on the innocent globe. I’d love to read an interview with Gaia in which she says that her goal all along was to come up with a species that could produce Beethoven and make rockets to send the music deep into space. Now that’s something to make the other planets sit up and take notice. You think the point is merely to provide a home for thirty billion varieties of insect? I can’t tell you how much they itch. Sorry about the earthquakes, but it’s the only way I can scratch.

I do believe in a teleology, and this belief is not scientific at all.

And there’s nothing wrong with that.

Everything You Know Is Wrong

…about greenhouse theory?

Miskolczi’s story reads like a book. Looking at a series of differential equations for the greenhouse effect, he noticed the solution — originally done in 1922 by Arthur Milne, but still used by climate researchers today — ignored boundary conditions by assuming an “infinitely thick” atmosphere. Similar assumptions are common when solving differential equations; they simplify the calculations and often result in a result that still very closely matches reality. But not always.

So Miskolczi re-derived the solution, this time using the proper boundary conditions for an atmosphere that is not infinite. His result included a new term, which acts as a negative feedback to counter the positive forcing. At low levels, the new term means a small difference … but as greenhouse gases rise, the negative feedback predominates, forcing values back down.

And why is there resistance to his theory? Follow the money:

NASA refused to release the results. Miskolczi believes their motivation is simple. “Money”, he tells DailyTech. Research that contradicts the view of an impending crisis jeopardizes funding, not only for his own atmosphere-monitoring project, but all climate-change research. Currently, funding for climate research tops $5 billion per year.

Miskolczi resigned in protest, stating in his resignation letter, “Unfortunately my working relationship with my NASA supervisors eroded to a level that I am not able to tolerate. My idea of the freedom of science cannot coexist with the recent NASA practice of handling new climate change related scientific results.”

It’s always amusing, and frustrating, to hear people who attack skeptics ad hominem because they’re on the take from Big Oil or Big Coal, when places like the Competitive Enterprise Institute actually get very little of their funding from such sources. But climate researchers are always portrayed as objective, noble and selfless, unswayed by the need to maintain their grant funding stream from Big Climate Change. All I know is that I wish I was getting paid as much to be a skeptic as some apparently think I must be. Or getting paid at all, for that matter. But so far, not a single check has shown up in the mail from Exxon-Mobil or Peabody. It’s also an interesting story, in light of Hansen’s complaints that he was “muzzled” by the administration, all while he was going around giving speeches evangelizing to the faithful.

I also found this criticism underwhelming.

Dr. Stephen Garner, with the NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL), says such negative feedback effects are “not very plausible”. Reto Ruedy of NASA’s Goddard Institute for Space Studies says greenhouse theory is “200 year old science” and doubts the possibility of dramatic changes to the basic theory.

Yes, can’t be overturning two-hundred-year-old theories. That would be completely unprecedented in science.

[Update in the afternoon]

This cautionary essay about science journalism seems to be relevant: beware the underdog narrative.

I Always Suspected It

I’ve always thought that Monster cables were a scam, and that the supposed quality improvement couldn’t justify the ridiculously high prices, and that it was quite annoying that they’ve monopolized so much shelf space in the electronics stores. It’s hard to get reasonably priced audio cables (though things are better at Home Depot). But really, I’ve always figured that most people wouldn’t be able to tell the difference between Monster and lamp cord.

Well, it turns out that supposed audiophiles couldn’t distinguish between Monster and coat hangers. But I suspect that the scam will continue, with salespeople continuing to push them. There are probably great margins for both the manufacturer and the retailers.

A Cure For Diabetes?

It seems to work in mice:

Last year, Dr Terry Strom and his team demonstrated that they could stop the on-going destruction of insulin-producing beta cells in mice using a combination of three drugs, although they were unable to regenerate the cells.

However, when they added an extra ingredient – an enzyme called alpha 1 anti-trypsin – a significant rise in the number of beta cells was seen.

I’m not sure what the point is here:

It is exciting that these drugs could stop the immune system from attacking insulin-producing cells, but it is too early to tell whether these cells recovered in the mice or if new cells were produced.

Does it matter, from a practical standpoint? I can understand why the researchers would be curious, but a cure is a cure.

Anyway, here’s hoping that it can work in higher mammals.

Proves Her Point About The Math Thing

Charlotte Allen is embarrassed to be a woman. She gets the math wrong here, though:

Women really are worse drivers than men, for example. A study published in 1998 by the Johns Hopkins schools of medicine and public health revealed that women clocked 5.7 auto accidents per million miles driven, in contrast to men’s 5.1, even though men drive about 74 percent more miles a year than women.

Since the statistic is on a per-mile basis, the fact that men drive more miles a year is irrelevant. So the disparity–5.1 versus 5.7–is actually quite small, and perhaps within the statistical error.

Of course, the thing that statistics like this don’t reveal is how many accidents they cause, unbeknownst to them, because they are oblivious to their surroundings. I’m always bemused by someone who I know to be a terrible driver bragging about the fact that they’ve never had an accident. Not to imply that men don’t do this as well, of course.

Eating Themselves To Death

A new theory about the end of the Neanderthals:

“TSE’s could have thinned the population, reducing numbers and contributing to their extinction in combination with other factors (such as climate change and the emergence of modern humans),” he said.

Such diseases have very long incubation periods, he further explained, so affected individuals may not show symptoms for a very long time. Similarly, people who consume TSE victims may not exhibit signs of illness immediately after eating.

“Neanderthals would have been unlikely to spot any causal relationship between cannibalism and TSE symptoms,” Underdown said.

No kidding.
